LED indicators The following indicators show the status of the controller: Relay1/Relay2 (green) – these LEDs are illuminated whenever the corresponding relay is activated (the NO contact is closed and the NC contact is open); Sts (red) – this flashes when the power supply is turned on; Log (yellow) – this LED indicates that someone is connected to the controller through the web interface; Link (green) – this LED is located on the Ethernet connector. It indicates that the device is connected to the network; Act (yellow) – this LED is located on the Ethernet connector. It flashes when activity is detected on the network. 6. Example Applications 6.1 Remote control The controlled device is connected in series with the relay contacts. Users can operate TCW121B using a web browser or SNMP application. Both relays are managed independently. TCW121B_R4 ( Firmware version 2.xx ) Page 3 6.2 Remote monitoring A relay contact of monitored device is connected to the digital input. When an event occurs – the controller can sends an e-mail and/or SNMP trap. 6.3 Data acquisition The TCW121B can be used in Data Acquisition Systems (DAQ). The device uses SNMP v.1 protocol for communication with monitoring and management software applications. 7. Installation Please follow the steps below for proper installation : 1. Mount the controller in a dry and ventilated place. 2. Connect the Ethernet port to a 10/100MB Ethernet network. For direct connection to a PC use a “crossover” cable. 3. Connect the I/O pins of the controller according to the required application. 4. Connect the power supply. TCW121B_R4 ( Firmware version 2.xx ) Page 4 If the red LED blinks, the power supply is OK. By default TCW121B comes with the following network settings: IP address: 192.168.1.2, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.1 Communication with TCW121B can be established by assigning a temporary IP address to the computer. This address should be in the same network (for example 192.168.1.3). To get access to the web interface, you should type http://192.168.1.2 into the browser. If the network settings are correct, the “Login” page will appear. 8. Web-based setup. The web based interface allows configuration, monitoring and control. Recommended browser is Internet Explorer at 1024x768 resolutions. 8.1 Login page After opening the Login page, authorization data must be entered (by default username=admin , password=admin). It is recommended to change the username and password to prevent unauthorized access to the controller. The controller supports one active session – only one user can operate the device. If another user tries to login, the message “Someone’s logged in” appears: The active session will be terminated automatically, if the current user stays inactive for 2 minutes. TCW121B_R4 ( Firmware version 2.xx ) Page 5 8.2 Monitoring page After successful authorization, the “Monitoring” page appears: The “Monitoring” page provides information about the state of the relays and digital inputs, values of analog voltages (applied on analog inputs), temperature and humidity. The state of the relay can be changed by appropriate “ON/OFF” button. To change the state of relay for specified time “Pulse” button should be pressed. Duration of the pulse is specified in “Pulse Duration” field of “I/O Setup” page. 8.3 I/O setup page I/O settings can be made here. For temperature, humidity and analog value MIN, MAX and HISTERESYS values can be set. These values define the thresholds for all monitored parameters. When the measured value goes out of range SNMP trap or e-mail (if enabled) will be sent. Leaving range is considered when the parameter goes lower than MIN values or higher than MAX. Coming back in the range is considered when the parameter goes higher than (MIN + HISTERESYS) or lower than (MAX – HISTERESYS). TCW121B_R4 ( Firmware version 2.xx ) Page 6 For digital inputs, conditional e-mail sending can be arranged by following part of the page: Relays can be activated automatically depends of value of monitored parameter (humidity, temperature, analog voltage and changes on digital inputs) or manually. Only one parameter can be assigned for relay activation, at the same time: When manual activation is selected, “Pulse” and “ON/OFF” buttons on “Monitoring” page are active. The duration of pulse for relay activation can be set from 1 to 253 seconds. For all monitored parameters only one e-mail recipients can be set. Automatic monitoring page refresh interval can be set from 1 to 253 second. If 0 is chosen – the monitoring page will not refresh automatically. 8.4 Network Setup page The Network parameters are set on this page. The following parameters can be changed: IP configuration – IP Address can be static or dynamic (DHCP server should be present in the network); IP address, Subnet mask , Default gateway – these fields are active if IP address is static; DNS – these fields is mandatory, if domain names are used instead of IP addresses. By default DNS has the same Ip address as Default gateway; Time Server and Time Zone – these fields are not mandatory, they are used when e-mail must be sent; Host Name – up to 16 symbols, it appears as a “Subject” in sent e-mails; MAC – device MAC address. TCW121B_R4 ( Firmware version 2.xx ) Page 7 The good practice is to change the default IP address of controller immediately after first power-on. This will avoid collisions if many devices are used in the same network. It may be necessary to clear the arp cache, each time you connect a new device to the network. This is done by typing arp -d in the command prompt window of computer. To set up the SMTP server details, the following fields should be completed: Mail server [IP:port] – domain or IP address and port of SMTP mail server; E-mail – sender e-mail; Username and Password – authentication details for mail server. When configuring the Mail server, note that TCW121B does not support SSL ( Secure Socket Layer). Username and password for WEB access can be changed in the Web Access section. Setting the authentication to “disabled” will provide access to monitoring page without entering user name and password. The HTTP port can be changed also in this section. XML/HTTP API section controls the access to XML file and HTTP commands. Detailed information can be found in chapter 15 “XML and HTTP API commands”. 8.5 SNMP Setup page TCW121B supports SNMP v.1. This enables the device to be part of large monitoring and control networks. The possible settings for “SNMP” section are: SNMP Configuration – enable/disable SNMP; SNMP Port – allows standard port changing; Write/Read community – performs client authentication; SNMP Traps – enable/disable SNMP trap messages; IP address – IP address of the receiving host; Community string – performs client authentication; Trap Interval - time interval in seconds for SNMP trap messages; TCW121B_R4 ( Firmware version 2.xx ) Page 8 Max. Traps number – maximum number of SNMP trap messages sent, if trap condition is present. SNMP traps are sent if: event occurs (status change) on Digital Input 1 or Digital Input 2; measured voltage on Analog Input 1 or Analog Input 2 goes outside the range; measured temperature goes outside the range; measured humidity goes outside the range; restart condition. 9. SNMP setup TCW121B can be configured and monitored through SNMP (Simple Network Management Protocol). This could be done using every SNMP v.1 compatible program. Parameters that can be changed, are grouped according to their functions in the tables below. To obtain a valid OID number it is necessary to replace the “x” symbol with ”1.3.6.1.4.1.38783”. To save the changes configurationSaved (OID x.3.13.0) should be set to "1". 9.1 9.2 Product OID Name Access Description Syntax x.1.1.0 name read-only Device name String x.1.2.0 version read-only
